Specification ofA Letters Patent.

Patented June 2, 1908.

Application filed April 8, 1907. Serial No. 367,121.

T all 'whom "it may concern:

Be it known that I, THOMAS W. MORRELL, a citizen of the United States,residing inthe town of Bloomfield, county of Essex, and State of NewJersey, have invented certain new and useful Improvements in Machinesfor Producing Cames, of which thefollowing is a specification.

My invention has forits object the provision of a machine for operatingin a continuous manner upon an endless strip of metal of suitable crosssection for the productionA of cames, and particularly the production ofan improved came which is not claimed herein, but which forms thesubject matter of an application iiled by me on the 11th day of March,1907, Serial Number 361,804 and in which the operations of indenting theweb and flanges of the strip may be carried out very expeditiously.

Reference is hereby made to the accompanying drawing of which Figure 1is a plan view of a machine constructed in accordance with my invention.Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a section on line 33 of Fig. 2. Fig. 4 is a section on line 4 4 of Fig. 2. Fig. 5is asection on line 5 5 of Fig. 2. Fig. 6 is a section on line 6 6 of Fig.2. Fig. 7 is a per'- spective view of the carrier for conveying thefinished cames. Fig. 8 isa section on line 8 8 of Fig. 2. Fig. 9 is adetail sectional view of a portion of the traveling came strip showingthe rolls for indenting the flanges thereof. Fig; .10 is a sectionalplan-view of a portion of one of the finished cames showing theindentations thereof. Fig. 11 is a section on line 11-11 of Fig. 9. Fig.12 is a perspective view of the receptacle into which the 'finishedcames are to be packed.

Referring to Figs. 1 and .2, the endless strip 1 from which the camesare formed travels from left to right, this strip being in the form of adouble channel or I having a vertical web and top and bottom flanges oneither side thereof. This strip occupies a horizontalposition restingupon the supporting table or bed 55 and between the op ositely disposedrollers 4, 4 carried by thek atcrally adjustable guides 3, 3 and similarpairs of rollers 15, 15 carried by the similarly adjustable guides 14,14. Between the two sets of guides referred to is a pair of i'lutedrolls 5, 5 mounted upon vertical spindles y45 and 48 suitably journaledin the mainframe 7l. These rolls are of such size that the teeth formedupon their peripheries indent the vertical web of the came stri as itpasses 'between them, and as these ro ls are positively driven by amechanism which will be described later, they serve to' feed theV stripforward through the apparatus. The rolls` 5 are. secured upon the upperends of the spindles 45 and 48 by keys 81', so that they may be readilyremoved and replaced by rolls of different size whenever it is desiredto operate upon stripsv of different thickness. I

After leaving the iiuted rolls 5, the traveling strip passes between agroovedv supporting roller 49 adapted to fit the rounded surface of thestri as shown in Fig. 4andapair of oppositely ofisposed fluted rolls 9,9 which are mounted upon the'ends of arbors'79', the latter beingremovably secured in sockets formed in' the ends of the spindles 53" byset screws 80, (see Fig. 11). These rolls 9 are adapted to formindentations in the bottom flanges 8 of the traveling strip 1, theroller 49 acting 'as a support to coperate with the fluted rolls in theformation of said' indentations and the apparatus is designed to operateupon came strips whose flanges are of different thickness to produceindentations of any desired depthL by means of an adjustment of theroller 49 and spindles 53 shown most clearly in Fig. 4. i journaled in aframe 52, the ends of which engage vertical guides in the main frame 71and may be adjusted vertically by means of adjusting screws 54. Theroller 49 is supported by al frame 50 which moves in vertical guidesformed inthe frame 52 and is vertically adjusted by the adjusting screw51.

The traveling strip 1 next passes between the fluted rolls 12, 12 andthe grooved roller 56.(Fig. 5) which parts .serve to form indentationsin the upper fianges of the strip in a manner exactly similar to that bywhichI the indentations are formed in the lower flanges as' has beendescribed. The arbors of the rolls 12 are removably held in sockets inthe spindles and the latter are journaled'in the frame 59 which moves invertical guides in the main frame 71 and is adjusted vertically by meansof adjusting screws 61:; the roller i 56 is journaled in the frame 57which moves in verticalguides in the frame 59 andis held in variouspositions of vertical adjustment by the adjustin screw- 58.

The trave ing strip 1 having passed the three sets ofl indenting rollsand the lateral guider'ollers 15, reaches' the end'of the table Thespindles 53 arek frame 55 and passes thence into one of the grooves 16of the rotary carrier 17. When it reaches the end thereof it is severedby a quick movement of the knife 2O which is double edged and cuts firstin one direction and then the other, moving with a quick powerful actionproduced by mechanism which will be afterwards described, the saidmechanism however being so correlated with the feed rolls 5 as to cutofl from the endless `ystrip sections ofv uniform length. That portionof the moving strip which is thus severed at this moment occupies thegroove 16 formed in the periphery of the revolvingl drum or conveyer 17,and this conveyer is a periodically rotating member which serves toconvey the rcut lengths in a direction transverseto that in which theendless strip travels, the cut lengths being therefore continuouslyconveyed to one side as shown in Fig. 5, being prevented from leavingthe groove 16 by a curved guard 25 until the chute 26 at the lower edgeof said guard is reached, said chute being preferably integral with theguard as illustrated. Upon reaching the said chute the weight of thecame causes it to enter the chute as shown in Fig. 8. ln this view thecame is shown as being held by a shoulder upon a spring member 40 ofwhich there are a number at regular intervals along the width of thechute (see Fig. 1).

removable chute 27 is adapted to be applied to the fixed chute 26 so asto receive a limited number of the finished cames from the said chute.The removablel chute is preferably constructed as follows: A series ofup er strips 29 and lower strips 30 spaced laterfflly, are secured atone end to a cross bar 84 by means of bolts 85 and thumb nuts 86. Thedistance between the two sets of strips may be varied by theuse of oneor more washers 87, to adapt the chute to cames of different sizes. Thestrips 3() are preferably covered with a sheet of moisture proof paperor other packing, such as wax or paraffin paper and serve as a slopingtable to receive and support the cut cames. Upon the ends of the crossbar 84 arepintles 33 and which are adapted to rest m sockets 34 mountedon standards 35 while the free ends of the strips 30 rest upon fingers32 carried by the fixed chute 26, and when the removable chute occu iesthis position the ends of the strips 29 frce the springs 40 upward asshown in Fig. 5 so as to permit the cames to slide freely from the chute26 into the chute 27. I

' The mechanism for operating the various moving parts is as follows:Power is applied to the drive pulley 41 on the end of the shaft 42,Figs. 1, 4 and 6. This shaft is suitably journaaled in bearings carriedby the main 71 and is provided with bevel gears 43 and 62. The gear 43drives the bevel gear 44 which is rigid with the spur gear 46 mounted onthe lower end ofthe vertical shaft 45 which carries the fluted roll 5and is journaled in the main frame. Meshing with the gear 46 is asimilar spur gear 47 which is mounted on the lower end of the verticalshaft 48, also journaled in the main frame. The bevel gear 62 mesheswith a similar gear 63 secured to one end of a horizontal shaft 64 whichis journaled in the main frame and carries at its opposite end a cam 65for operating the knife 20 (see Figs. 2, 6 and 8).

This cam is adapted to operate transversely movable rods 68 and 69 whichare pivoted at one end on a pin concentric with the axis of the cam andwhose free ends are mounted in rectangular openings formed in uprights70 of the main frame 71. Projections 66 and 67 are formed upon said rods68 and 69 respectively and are pressed against the surface of the cam bya spiral spring 72 which is secured at its respective ends to flanges orprojections 73 and 74 formed respectively upon the rods 68 and 69. Theshape of the cam is such that during half of its rotation beginning forexample, in the position of Fig. 8, it moves the rod 69 towards theright thereby placing the spring 72 under elastic stress and then holdsthe rod 69 in a stationary position for another half revolution at whichtime the abrupt shoulder of the cam allows the spring 72 to move the rod69 towards the left with a rapid hammer blow of the flange 74 upon theend of the rod 76, one end of which is guided by the pins 78 carried bya cross member of the main frame 71 and the opposite end of which ispivoted on a pin 77 carried by the frame or support 21 of the knife 20,thereby causing the knife to move very rapidly and forcibly from rightto left (see Fig. 8) until it occupies the position shown. During thistime the cam has held the rod 68 in the )osition shown during half arevolution, at w ich time the shoulder of the cam passes the rojection66, and the rod 68 is moved forcibly to the right by the spring 72. Thisaction causes the flange 72 to strike the end of the rod 75 which movesbetween another set of guide pins 78, also carried by the cross memberof the frame 71 and which is pivoted upon the pin 77 similarly to therod 7 6, thereby moving the support 21 and knife 2O rapidly and forciblyfrom the position of Fig. 8 towards the right. During this movement thea propriate pawl 23 engages the ratchet whee 24, and turns the conveyerdrum 17 a distance of one tooth. Upon the reverse stroke of the knifesupport, the otherpawl 23 will move the drum 17 a distance of anothertooth in the same direction. The mechanism is so timed that the strip 1is fed such a distance beyond the cutting point as to form a came of thedesired length.

The operation of the machine is briefly as follows: An endless travelingstrip 1 of suitable cross section, is fed along the surface of the table5, 5 and between the guide rollers 4, 4 indenting rolls 5, 5 9, 9 12, 12and guide rollers 15, 15 until the forward end of the strip reaches thefar end of the rotary conveyer 17; the knife 20 then moves rapidly so asto sever the traveling strip, and the movement of the eonveyer then.carries the cut length in a lateral direction. The end of the travelingstrip then enters the succeeding groove 16 of the traveling conveyer 17and when it reaches the far end thereof, the knife 20 moves in a reversedirection and severs a second length, the cut lengths being continuouslytransferred by the rotary conveyer to the fixed chute 26 through whichthey slide by gravity into the removable chute 27 until the same isAfilled. The attendant then removes the said chute 27 and places it uponthe bottom of a receptacle 3o which is lined with waxed paper 37 (Fig.5). A pair of vertical rods 38 are then introduced through the openings39 formed in the chute 27 and openings 89 of the receptacle 37 into theioor 88. The operator then withdraws the removable chute by drawing thesame in a direction transverse to the length of the cames and the rods38 hold the cames and the sheet of pa per 28 upon which they restagainst withdrawal so that they remain within the receptacle 37. Theremovable chute is thus unloaded so as to be entirely empty and ready toreceive a fresh sheet of paper28. It is then applied to the fixed chute26, the pintles 33 resting in the sockets 34. As soon as the chute isagain Jlled it is placed in the receptacle 37 on top of the layer ofcames previously deposited and is withdrawn in the manner previouslydescribed lso as to leave a second layer of cames separated from thefirst layer by a sheet of waxed paper as shown. These operations arecontinued until the receptacle is entirely filled, when the rods 38 arewithdrawn, the paper 37 folded over the cames and the receptacle closedby moving the side 90 and cover 92 on the hinges 91 and 93,A theapertures 94 of the cover receiving the pins 95 and the hasp 97 having aslot 98 being closed upon the staple 99 and secured by a pin 100 (Fig.8).
